Rose plant Jacfed
This present invention relates to a new and distinct variety of rose plant named Jacfed of the hybrid tea class which was originated by me by crossing the variety Grand Masterpiece, U.S. Plant Pat. No. 4,767, with the variety First Federal Renaissance, U.S. Plant Pat. No. 4,459. 
     The primary objective of this breeding was to produce a new rose variety having the large flower size of Grand Masterpiece and combine this with the early flowering of First Federal Renaissance. The objective was substantially achieved along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents as well as from all other varieties of which I am aware: 
     1. Very large, high centered flowers. 
     2. Many small thorns on new and old wood. 
     3. Susceptible to powder mildew. 
     4. Heavy petal substance. 
     5. Deep glossy green foliage. 
     6. Vigorous upright growth. 
     7. Exhibition quality of blooms. 
     Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing characteristic and distinctions come true to form and are established and transmitted through succeeding propagations. dr 
     The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character. 
    
    
     The following is a detailed description of my new rose cultivar with color in terminology in accordance with the Royal Horticultural Society Colour Chart except where ordinary dictionary significance of colir is indicated.
